METALLIC gema Specification of Letters Patent.

Application filed April 5, 1913. Serial No. 759,089.

espeeially adapted for use in the eonstrue- .y

tion ot' springt mattressesbed bottoms. and the like. in wliu-li longitudinal metal ribbons or .slats are interwoven with wires uniformly disposed at propei` intervals along the lon- `ritiidiiial extent thereof: the longitudinal members being suspended in a relatively rigid trame b v vsprings attached to each end bers.

'ot eaeh of themembers and spared apart at points ot attaehmentio saidtraiue and at inteij'valsby the tiainsverse, :itl fwi're ymem- Souie ot" the objects otn'iy invention are tofsernrethe i-'ibboi'i-like longitudinal slat` members, at intervals to traiisi'erse staf. members ronnmsed. preferably. ot" wire,l and to key the parts serurelytogether bv an'- othei' wire: thereby to enhant'e the resiliency ot the structure: to spare apart anilv maintain the longitudinal-membei's in Iii-oper ie- 1 lation by tiaiisvei-sely exteni'ling' wires. the resilirnev ot' whirh will permit some relative liinjritiulinal movement ot the slatted members. and at the saine time prevent any lateral ifelaliie movement thereof; and to ejem-rally improve such striutui'es by inweas-inel the .ilien y, durability. and wear without iiiateiiallv inrieasingf the enst of eenstrurtioii.

Further objeets'ai'ul advantages ot my invention will beeome readily apparent to persons skilled in tie art. t'roin a consideration ot' the following deseription when taken in ronjiinetion willi the drawings. and the novel Jfeatures thereof will be speritieally defined in the appended Aelaims.

In using' my slatted fabric for bed-bot toms.'- spring mattresses. or the like, I pro- ;Vvdefa rigid traine 10, to `which the longitudinal members of the structure 11 are attached at' stated intervals. as by springs 1212 There are two oppositely disposed framemenibers 10 in a bed bottom and 'each end ,of thel longitudinal member 11 is attaelied thereto -bv means of a spring 12, so that each ot the longitudinal members is ,inf dependentlr suspended in the frame .by

Vin `.ans of the spi-ings. By this arrangement 'the longitudinal members ll are uniformly spaeetl'apart throughout the entire transverse dnnensionsof the structure. To maili- Patented Maly 27, 1913. v

tain these members in proper spaced relaf' tion throughout their length, l provide fin-l terinediate transverse stay members p'nsed of wiresl?) and All whielrextend t'e'riyals across the' longitudinal inenib'er` '.lhelongitudinal iiieinners 1l are perfo u `atfinterrals. to provide slots' 15."A The trans "if'el'irfe slay nieui'bers are eoiiipesedo't', tires Il `and '14. The -wire llJisiIitended'tolie "fiipon the top of the slats llafiiidfat pr r "intel-vals.is bent'into loops 16 'to "proiiidel" eyes l?. The elves 1T are in the same plane as the axis of the parallel wire 13.

ll'hen the longitudinal members l1 are assembled the respective Dei'forations 15 of all ot the members are in the same transverse plane, so that in the-act ot assembling, the stay wires 1l. have their loops 16 passed through the slots l5 of the longitudinal members l1. the ends of the wires 14C being turned haelt upon the slat 11. as at- 18, so that Ythe end 19 thereof is tucked away to beout of possible Contact with passing 0bjeets. The key-rod or wire 13 is then passed through the eyes made. in the series of loops lt' of the wire l-t and under the longitudinal cross members 11. After the key-rods have been passed through the eyes of all the loops 16, the ends of the key-rods are inturned throii h the terminal loop 16, as shown at 20. y this means all of the raw or sharp terminal surfaces of the Wires are intiiriied so as to be ont of the way and nothing but smooth round surfaces are exposed to Contact. The key rods 13 are passed through the loops 16 for the purpose of holding the wires 14 in proper relation with respect to the longitudinal members 11 and to retain the loops within the slots made in said longitudinal members;

, otherwise the Wires 13 could be readily dispensed with. The loops 1G are made at' right angles to the axis of the wire 14 so that the slots 15 made in the longitudinal members 11 may have their longest dimension parallel `with the sides of the members instead of transversely thereof, whereby the possible weakening of the slot 11 is avoided.

Any weightthat may be imposed upon a given longitudinal member 11, tordcause it to be downwardly deiected to a greater extent than its associate members, Will cause the lateral detiection of the transverse stay members 13 and 14 suiiiciently to permit the said downward movement of the longitudinal members, and the resiliency of the staf,v members Will cause it to come back into line when the .Weight has been removed from the longitudinal member, thereby permitting relative longitudinal movement of the longitudinal members under extreme roni'lilioi'is of use without disturbing the relatively rigid connections between the the combination of a plurality of parallel slats uniformly spaced apart and perforated at regular intervals;.transverse stay members eomprisingwires having loops at uniform intervals to provide eyes in the axial plane of the respect-ive stay Wires for engagement in the perforations in the slat members; and key-rods threaded through said eyes and located on the opposite sides of said slat members.

Q. In a device of the character described, the combination of a relatively rigid frame having opposite end members perforated at regular intervals; a plurality of slats perforated at regular intervals, said slats independently supported in said frame b v springs engaging each end thereof; transverse stay members comprising wires having loops at uniform 'intervals to provide eyes in the axial plane of the respective stay Wires for engagement in the perforations in the slat members; and key-rods threaded through said eyes and located on the opposite sides of said slat members.

In testimony whereof I hereunto set my hand` in the presence of two Witnesses.
